The writ petitioners regularization will be decided as per rule 4, and their seniority and promotion will be governed by Rule 8 of the Rules, 1981.

Teachers and Non-Teaching Staff of the Nationalized Colleges (Directorate of Public instruction) Absorption Rules, 2000
Rule 6(5)
The Bangladesh Public Service Commission recommended for regularization of the writ petitioners services as per Rule 6(5) of Rules, 2000 presumably on the ground that since the Rules of 1981 have been repealed, the Rules of 2000 will hold the field. There is totally based on misconception of law. The Writ Petitioners regularization will be decided as per rule 4, and their seniority and promotion will be governed by Rule 8 of the Rules, 1981.

The Government having itself decided to remove the anomaly in the matter of absorption of teachers like the respondent in the nationalised colleges and it never having been contended that the Government changed its decision for any good reason, the Court will be justified in holding that the Government is required by law to implement its· own decision.
